Americans pronounce lifecycle as LAHYF-sahy-kuhl (/ˈlaɪfˌsaɪkəl/). The L in "lifecycle" is a dark L — the back of the tongue rises toward the soft palate, adding a small "uh" quality before the L. This is called the Dark L vs Light L, and it's one of the defining features of casual American English. It comes out as LAHYF·SAHY·kuhl. Stress falls on the first syllable — keep everything else short and quick. You'll hear it in sentences like "The lifecycle of a butterfly includes the caterpillar and pupa stages".

Place the tip of your tongue against the alveolar ridge just behind your top front teeth, the same contact point as /t/, /d/, and /n/. The difference is what happens to the air: for /l/, you let it flow continuously around the <em>sides</em> of the tongue (that's why /l/ is called a lateral). Turn your voice on the whole time. Lips stay relaxed, no rounding or flaring. For the Dark L variant at the end of a syllable, also pull the back of the tongue up and back toward the soft palate.
Start with your jaw open wide and your tongue resting low and flat. Glide the front of your tongue up toward the roof of your mouth as your jaw closes halfway.

The textbook way isn't wrong — it's just not how anyone actually says it.
